WeeFin is a French impact fintech created in 2018 with a mission: to raise the standards of sustainable finance and make it the norm. Convinced that sustainability should be at the heart of every investment decision, we have created the first SaaS technology 100% dedicated to sustainable finance, enabling financial institutions to industrialize their entire ESG and impact operational chain: from ESG data collection to regulatory reporting and indicator calculations.

Specifically, our platform allows:

1. Collecting ESG and impact KPIs while ensuring their quality
2. Accelerating transformative ESG processes through collaborative interfaces (e.g., coal exclusion, engagement with companies to accelerate their transition)
3. Creating ESG and impact criteria that reflect client values and are shared across all teams

Our goal: to make the daily operations of financial institutions easier so they can deploy ambitious sustainable investment strategies at scale.
